I've had my T100 new since august 2017, and its always lived outside and I've always done short journeys- now over the last few weeks battery keeps on going flat. Recharged battery on weds with optimate charger and measured voltage across terminals with voltmeter ( 13.7), bike started fine, drove one journey of 3 about miles and another of around 2. Measured voltage today ( sunday) and its down to 12.6 and bike wont start ( almost did ! )… Should it lose its charge after two starts and 3 days resting ? Battery obviously isn't totally knackered as it does take charge from optimate. Any ideas folks-how do I check if the bike is charging the battery P.S no extra electrical gubbins fitted like heated grips- just bog standard factory spec
I'm no expert but would suggest that with journeys that short there is no way the battery has time to recharge Couple that with the fact it is kept outdoors and not plugged in to any form of battery maintainer like an Optimate in these colder conditions and I would absolutely expect the battery to discharge to an extent
my optimate is supposed to indicate if its sulphated and go into recovery mode. It just shows " charging " and eventually after 24 hours goes to steady green light for "charged". Thanks for advice about what voltage- will give that a go tomorrow. I know I had a similar problem on a classic mini a few years back and turned out to be a bad earth ,,,,!
ended up getting new battery, 5 days of optimate charging and the thing still wouldn't start. Anyway new battery in today and it showing around 14+ v at 3000 rpm, so hopefully just battery buggered..
